Dummy 13 Scale Olympic Barbell Set V2 - Display your PR! - For MMU or single color

V2 is updated to include 10Lb and 5Lb weights, a chamfered edge to make it easier to tell edge to edge plates apart, improved fit tolerances, and a bar with integrated gripping hands.

Per izkariot_438646's suggestion, I've also added a couple of easy-print options for the bar.

Bar notes:

As Soozafone's original model suggests, PLA and PETG joints get sloppy, so I recommend ASA or ABS for the bar/hands. I suggest 3 perimeters and 15% Infill. 

For best results use PVA or PVB soluble support. 

PLA with PETG, or ASA/ABS with Breakaway80 from xypolyer will work well too.

Support with 2mm spacing at 90°, 2 interfaces at 45°, slow interface speed down to 20mm/s for best cooling and minimal bonding. This works with single material prints too, but requires more cleanup.

Plate notes:

Plates are embossed with weight. If you have MMU, white on black or black on silver looks great. 

Up close, the 5 and 10Lb plates are cramped, so the text will be mostly illegible on a .4mm nozzle. I haven't tried with a .2 or .25 yet, nor have I played around with text heights yet to see if I can clean this up, but will update if I find a clean fix. 

2.5Lb plates were just too small for the text, but if you want to add them, the scale factors for the 5Lb plate would be .66 Z and .85 for X and Y. I suggest removing the text for this.

.3mf works best for MMU because the text is saved as separate parts for coloring, and it makes it easy to select the lettering for a specific color. This way, you can also remove the text or adjust depth to get the best look with your specific printer, or even scale them for a different look.

General Notes:

Plate scales were based on the following dimensions:

• 45 lb Plate - Outside Diameter 17.75" | Thickness 1.5"
• 35 lb Plate - Outside Diameter 14" | Thickness 1.5"
• 25 lb Plate - Outside Diameter 11" | Thickness 1.5"
• 10 lb Plate - Outside Diameter 9" | Thickness 1"
• 5 lb Plate - Outside Diameter 8" | Thickness 0.75"
• 2.5 lb Plate - Outside Diameter 6.5" | Thickness 0.5"

Bar dimensions were based on: 

• Grip thickness Ø1.17"
• Length 86"(7.2ft) 
• End Ø1.96"

With standard open hands, this set works well for deadlift, overhead press, and bench poses, but I like the hands to be an integral part of the bar for better stability and for a more realistic grip.

I have a matching adjustable, scale bench available here: https://www.printables.com/model/1098839-dummy-13-weight-bench
